Abstract: A touch module includes a casing, a touchpad, a supporting plate and a rotatable mechanism. The touchpad is installed in a first accommodation structure of the casing. The rotatable mechanism is pivotally coupled to a second accommodation structure of the casing. The supporting plate is movably installed on the casing, and combined with the touchpad. The second accommodation structure is extended from a specified side of the first accommodation structure. There is a horizontal gap between a lateral edge of the touchpad and an inner wall of the first accommodation structure corresponding to the specified side. While the touchpad is moved through the horizontal gap, a linking terminal of the rotatable mechanism is pushed by the touchpad or the touchpad is moved away from the linking terminal. Consequently, a stopping terminal of the rotatable mechanism is correspondingly inserted into or detached from the vertical gap.

Abstract: A touchpad module includes a circuit board, a switch and a conductive raised structure. The circuit board includes a first conducting part and a second conducting part. The switch is installed on the circuit board. The switch includes a metal dome. The metal dome includes a first portion corresponding to the first conducting part and a second portion corresponding to the second conducting part. When the metal dome is subjected to deformation, the first portion of the metal dome is contacted with the first conducting part. The conductive raised structure is arranged between the second conducting part and the second portion of the metal dome. Since a gap is formed between the circuit board and the second portion of the metal dome, the contact area between the metal dome and the circuit board is reduced. Consequently, the generated noise is reduced.

Abstract: A touch module includes an upper plate, a lower plate, a hinge structure, an elastomer and a touchpad assembly. The touchpad assembly is located over the upper plate. A first end of the upper plate and a first end of the lower plate are pivotally coupled to each other through the hinge structure. While the touchpad assembly is pressed down, a second end of the upper plate is swung downwardly relative to a second end of the lower plate and a switch element of the touchpad assembly is triggered. When the touchpad assembly is no longer pressed, the elastomer provides an elastic force to the upper plate. In response to the elastic force, the second end of the upper plate is swung upwardly relative to the second end of the lower plate and the touchpad assembly is returned to an original position.

Abstract: A touchpad module includes a substrate, a touch member, a switch, an elastic element and at least four protrusion structures. The substrate includes at least four first openings. A bottom surface of the touch member faces a top surface of the substrate. The switch is coupled with the bottom surface of the touch member. When any point of the touch member is pressed down, the switch is in contact with the substrate. The elastic element includes a fixed part and a movable part. The fixed part is coupled with a portion of a bottom surface of the substrate. The movable part is arranged around the fixed part. The movable part is located beneath the at least four first openings. The at least four protrusion structures are coupled with the touch member and inserted into the corresponding first openings.

Abstract: A touchpad module includes a touch member and an elastic member. The touch member is disposed within a fixing frame of a computing device. The touch member includes a recess. The recess includes a first end and a second end. The elastic member is installed in a casing of the computing device, and includes a first elastic part, a second elastic part and an intermediate part. A portion of the first elastic part and a portion of the second elastic part are extended into the fixing frame, and contacted with the first end and the second end of the recess, respectively. When the touch member is moved from an initial position to a first position in a direction toward a first lateral wall of the fixing frame in response to an external force, the computing device executes a first function.

Abstract: A control module includes a frame structure, a touchpad assembly and a hinge structure. The touchpad assembly is located over the frame structure. The hinge structure is arranged between the frame structure and the touchpad assembly. The hinge structure includes an elastic plate and a supporting element. An end of the elastic plate is connected with the touchpad assembly. The supporting element is disposed on frame structure and connected with the elastic plate. Due to the elastic plate, the touchpad assembly is swung is swung along a fixed direction. While the touchpad assembly is pressed down, the end of the elastic plate is correspondingly swung. Consequently, the touchpad assembly is swung stably, and the touch module is operated stably.

Abstract: A touchpad module includes a touch member, a bracket, an elastic element and a spacer. The bracket is located under the touch member. The elastic element is arranged between the touch member and the bracket. The spacer is arranged between the elastic element and the touch member. While the touch member is pressed down, the touch member is moved downwardly to compress the spacer and the elastic element is pushed by the at least one spacer. Consequently, the elastic element is subjected to deformation and extended toward the corresponding perforation. The present invention further provides a computing device with the touchpad module.
